Abstract: A halftone threshold matrix includes a plurality of submatrices, wherein a first group of the plurality of submatrices has a line screen frequency different from a second group of the plurality of submatrices. The halftone method and apparatus removes the restriction that at most one pel is turned on per basic cell for the next constant input level and allows the pels in some basic cells to be turned on much sooner that the corresponding positions in other basic cells. This creates a dominant low frequency line screen simultaneously with the higher frequency line screen of the other basic cells. The present invention also allows the basic cells inside the threshold matrix to have different shapes and sizes. Thus, the cells participating in the low frequency screen could be larger than the cells generating the higher frequency screen. for example, the low frequency screen's pleasing patterns can distract the eye from noticing less pleasing patterns in the high frequency grid and vice versa.

Abstract: Provided are a method, system, and article of manufacture for using operation codes to control a decoder to generate data from an input data stream into an output data stream. An encoder generates an input data stream for a decoder comprising at least one operation code and compressed data for an output device. The at least one operation code instructs the decoder on how to process the compressed data. The decoder receives the input data stream and processes the data in the input data stream according to the at least one operation code. The decoder decodes the compressed data into decompressed data to send to an output data stream to the output device.

Abstract: Further compression of data allowing economical storage of data for extended periods of time in high-speed access memory is performed in reduced time by performing further compression during transcoding in the transform domain and without restoring image data to its original image data form. The reduction in processing time is achieved by exploiting the large number of zero-valued quantization transform coefficients and not changing quantized transform coefficients at zig-zag scan positions where non-zero coefficients are rare during range reduction of the entropy decoded quantized transformed data. The range can be restored by computation or estimation of an altered quantization table which is stored with the further compressed quantization values. Further advantages accrue from use of JPEG packed format for the data during transcoding.

Abstract: Rapid throughput of still image compressed data (e.g. JPEG) is achieved for presentation of images in rapid succession for browsing or browsing by panning within large images by using a hardware decoder adapted for presentation of moving images to reduce the processing load which must be performed in accordance with software although the still image data is incompatible with still image data in many respects; some of which necessarily lead to a loss of image fidelity. The still image data is partially decoded (e.g. entropy decoded) in software processing and re-encoded and reformatted to a form which can at least be accepted by the hardware decoder even though not compliant with any particular moving picture data standard (e.g. MPEG). Storage in the hardware decoder is reallocated to provide, in combination with a reduction of slower software processing, a throughput increase of four-fold or more.

Abstract: This invention solves problems due to employing error degraded data in digital processing. It particularly solves multi-generation problems wherein transform data degrade during each inverse transform and forward transform cycle even without any processing due to the rounding and clipping errors. It provides methods, systems and devices for reduced-error processing of transform-coded data. After inverse transformation of transform data, high-precision numbers are manipulated. The converting to integers and clipping to an allowed range steps are executed at any stage in the manipulation to obtain integer representation of the inverse transformed data such as for displaying of the data. However, further processing including forward transforming back to the transform domain is executed on the high-precision numbers. Thus, the rounding and clipping errors are not present in the processed data.

Abstract: Computation of variance or variance of the autocorrelation over a moving window of various sizes of a signal containing noise and possibly a small digital signal provides a sensitive, frequency independent indication of the likelihood of the presence of a small pulse, chirp or even spread spectrum digital signal possibly obscured by noise or larger signals in the signal to much lower signal-to-noise ratios than previously possible. Large signals in the signal which may also obscure any small signal are removed to a different signal path from the noise and small signals by subtraction after compression and reconstruction of the large signal. The compression noise thus added to the signal may also increase sensitivity of the variance of the autocorrelation to small signals obscured by the large signals. Controlling storage in response to the computed variance or variance of the autocorrelation allows substantial avoidance or limitation of storage of signals which contain only noise.

Abstract: A method and program product for conducting business transactions and avoiding inadvertent overdrafts. First, the value of an intended purchase is estimated and an electronic receipt is generated for the estimate. An account identified for payment (e.g., a checking account or a credit card account) is analyzed for sufficient funds and, alerts may be provided whenever the analysis indicates that the account has insufficient funds. As a result of the alert, the purchase may be halted or another form of payment may be selected. Also, total in-store purchases may be estimated and other accounts may be analyzed to determine if, in addition to being overdrawn for the selected account, the transaction is over budget.

Abstract: Brightness correction and image enhancement are derived to compensate for changes in captured image data by hardware scanners and the like by statistically measuring the captured data and generating or selecting a compensation quantization table to be substituted in image data encoded for compression. Three techniques of compensation usable singly or in combination are provided which may be used in combination with techniques for dynamic range reduction for extreme compression. Thus, improved images which may be enhanced in any desired manner, for example, to conform to an established image standard, may be derived from data having sufficient compression to allow economically acceptable long-term storage in high-speed access storage media even though the data captured is degraded in dynamic range, brightness and the like.

Abstract: Operations for decompression of compressed data is performed in parallel and in a pipelined manner to generate addresses into a memory on-the-fly rather than using a large look-up table. The logic circuits for doing so are thus reduced to the point of being able to be formed by suitable programming of a field programmable gate array (FPGA) while achieving substantial increase in processing speed beyond speed increases attributable to increase of clock rates.

Abstract: Method and system aspects for mapping tasks to iteratively improve task assignment in a heterogeneous computing (HC) system include identifying a current machine that defines a makespan in the HC system. Further included is the reassigning of at least one task from the current machine to at least one alternate machine in the HC system according to a predefined reassignment constraint. Reassigning also includes reassigning the at least one task when the at least one alternate machine can perform the at least one task in addition to previously assigned work while finishing in less time than the time of the makespan reduced by time required for the task being reassigned.

Abstract: An intermediate data format which is readily convertible to or from JPEG compliant data streams and to or from image data provides, in most circumstances, accelerated encoding and decoding in a degree sufficient to allow additional processing without necessitating increase of processor power even in relatively time-critical applications such as high-speed printers and image browsers. The format features flags which indicate if S>8 (indicating that extra bits are required to uniquely encode an orthogonal transform coefficient value) or runs of zero-valued orthogonal transform coefficients longer than sixteen are present in a block of data. The block of data can be tested for these conditions and flags set once per block or once per image. Extensive processing can thus be omitted if either or both of these conditions are not present, as will generally be the case.
